Hairballs begin as loose hair. A cat grooming herself passes her tongue over her coat, the barbs on the tongue pull free hairs loose, and most of that hair is swallowed. Some travels through and out, and some collects in the stomach until it comes back up. Brushing interrupts that chain at the only point you control: hair lifted into a brush is hair that never gets swallowed.
Short Coats: Weekly, but Thorough
A short coat sheds steadily rather than dramatically, and one proper session a week usually keeps loose hair from building up. Use a soft brush or a rubber grooming mitt and work in the direction of the coat, then once against it lightly to lift what the first pass loosened. Pay attention to the back, flanks and tail base, where loose hair gathers and where her own tongue returns again and again. The session can be short — five calm minutes beats fifteen forced ones — but it should reach the whole cat rather than only the easy back. During the heavier shedding weeks of spring and autumn, add a second session; you will feel the difference in how much hair the brush collects, and that collected hair is a fair measure of what would otherwise have been swallowed across the week.
Long Coats: Little and Often
Long coats hold far more loose hair, including a soft undercoat that a surface skim never touches. Several shorter sessions a week work better than one marathon, because the undercoat releases continuously. Comb in sections, parting the fur so the teeth reach down toward the skin, and clear each section before moving on. Work through the armpits, belly, trousers and behind the ears, where tangles form and trap still more loose hair against the skin. If you meet a mat, hold its base and tease it apart with fingers or a comb rather than pulling, and keep sessions paired with something she values — a favourite resting spot, a treat afterwards — so she offers herself for the next one. In shedding season, daily combing for a long coat is not excess; it matches the rate at which the coat is letting go. Tools follow the same logic in both cases: a fine comb that reaches the skin for long coats, a softer brush or mitt for short ones, and clean teeth and bristles, because a clogged comb skims over loose hair instead of collecting it. Empty the tool as you go; the pile it gathers is the visible score of the session.
Reading the Pattern, and Knowing the Limit
Keep a rough tally of hairballs across the month. A routine that is working shows in the tally: episodes space out as the brushing rhythm settles. An occasional hairball in a healthy, eating, active cat is a normal by-product of self-grooming, especially in long coats. The topic changes, though, when the pattern shifts. Hairballs arriving more and more often, retching that produces nothing, coughing or gagging that keeps recurring, or a drop in appetite alongside any of those are reasons to book a vet visit rather than reach for the brush more often. Frequent hairballs can point to skin irritation, over-grooming driven by stress or discomfort, or a digestive problem, and those need examination, not grooming. Note what you have observed — frequency, timing, her appetite and behaviour — and take that note with you. Through KinsLe, a household can share the combing rota fairly, with Care Teams recording who handled each session and when it happened.
